output format json

[Phaqui]

My use case is that I want to programmatically shell out to gut from a python script, to pull many repositories at once, and get results back of how many of them were actually updated. Therefore I want to be able to specify an output format that I can easily parse, such as json. Parsing the ascii tables seemed a little bit...frail.

Is there a way to do this, currently?

If not, I wrote an implementation of it that works, but I am not sure that I am completely happy with how it is structured..

The proposed WIP PR that implements this: #185
